Hello I installed openmpi-1.3.3 on my single node(cpu) intel 64bit quad-core machine. The compiler info is:

At the beginning, the execution of PW went on well, but after about 10 h, when the program is going to finish. The program hang there, but the cpu time is still occupied. (100% taken up by the program). There seems to be something wrong, somewhere. Any ideas? Thank you in advance.
